Subject: [PATCH 0/8] tty: n_gsm: Make mux work as a responder station

When using n_gsm you have to explicitly set it to work as a initiator
station. This led me to believe that it can also work as a responder.

In a use case where I needed responder station mux I came to the
conclusion that it actually does not work. Second and third patch
fix dealings with frame C/R bit that then enable mux to work as a
responder station.

Next patches in the series then fix bugs that were found after two 
instances of n_gsm connected over null-modem cable were used.

First patch fixes formatting errors, such as space before comma, and
most of the warnings reported by the checkpatch script.

Andrej Krpic (8):
  tty: n_gsm: fix formatting errors
  tty: n_gsm: fix C/R bit when sending as a responder
  tty: n_gsm: make mux work as a responder station
  tty: n_gsm: send DM response when accessing an invalid channel
  tty: n_gsm: replace dead code with a meaningful comment
  tty: n_gsm: add missing length field in control channel commands
  tty: n_gsm: properly format Modem Status Command message
  tty: n_gsm: Enable reception of frames separated with a single SOF
    marker
